La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.

Dockerized ffmpeg stops for no reason
2 mai 2023, par Arthur AttoutI'm trying to fire up a container that reads a video stream via
ffmpegand saves the stream as 30 seconds segments.

When I run the container, it stops after 20-ish seconds and returns with no error.


Here is my Dockerfile


FROM linuxserver/ffmpeg

Additional info :


- 

- The stream is up and running.
ffplay rtsp://192.168.1.85:8554/cameraopens normally - The exact command (from
ENTRYPOINT) on the host, works perfectly fine (it generates files for every 30 seconds). - From inside the container, I can ping 192.168.1.85 (it is actually
localhost) - Setting
-analyzeduration 1000does not fix the issue










Why is the container stopping for no reason ?


- The stream is up and running.

save a serial of images(cv::Mat) to a mp4 file in Variable Frame Rate mode by using ffmpeg library, how to set the pts ?
2 mai 2023, par ollydbg23In C++ code, I can correctly save a serial of images(opencv's
cv::Mat) to a mp4 file by usingffmpeglibrary, see the question and answer here : avformat_write_header() function call crashed when I try to save several RGB data to a output.mp4 file

Now here comes another question :


Rotem' answer in that question can have the
output.mp4saved correctly. When play the mp4 file, I see the frames(OpenCV'scv::Matimage) shows in a const rate.

What I can do if I have got the frames not in a const frequency, for example, the I got the first frame at the
0ms, and the second frame at the50msthe third frame at75ms, so that the each frame as associated time stamp, for example, those time stamp array are something like below :

int timestamp[100] = {0, 50, 75, ...};


What is the method to modify the Rotem's answer to reflect this ? It looks like I have to change the
ptsfield of eachframe. Because I just test the code, if I change this :

yuvFrame->pts = av_rescale_q(frame_count*frame_count, outCodecCtx->time_base, outStream->time_base); //Set PTS timestamp

// note I change from frame_count to frame_count*frame_count


Then the
output.mp4plays slower and slower, because the later frame has largeptsvalues.

Thanks.

Especially, I have those changes to the original Rotem's answer :


Fist, I have some code to generate a time stamp array :


// generate a serial of time stamps which is used to set the PTS value
 // suppose they are in ms unit, the time interval is between 30ms to 59ms
 vector<int> timestamps;

 for (int i = 0; i < num_frames; i++) {
 int timestamp;
 if (i == 0)
 timestamp = 0;
 else
 {
 int random = 30 + (rand() % 30);
 timestamp = timestamps[i-0] + random;
 }

 timestamps.push_back(timestamp);
 }
</int>

Second, I just set the PTS by those values :


yuvFrame->pts = av_rescale_q(timestamps[frame_count], outCodecCtx->time_base, outStream->time_base); //Set PTS timestamp


Note that I have set the fps like below :


outCodecCtx->time_base = { 1, fps*1000 }; // 25000
 outCodecCtx->framerate = {fps, 1}; // 25


Now, when I run the program, I got a lot of warnings in the console :

lavfi/dnn : Remove DNN native backend
27 avril 2023, par Ting Fulavfi/dnn : Remove DNN native backend
According to discussion in
https://etherpad.mit.edu/p/FF_dev_meeting_20221202 and the proposal in
http://ffmpeg.org/pipermail/ffmpeg-devel/2022-December/304534.html,
the DNN native backend should be removed at first step.
All the DNN native backend related codes are deleted.Signed-off-by : Ting Fu <ting.fu@intel.com>
